Samsung has launched a new range of hotel TVs. As well as superior picture quality, the sets make it easier for guests to plug in gadgets such as MP3 players. Research commissioned by Samsung last year into what guests want from their ideal hotel room revealed that two-thirds make their choice based on the "in-room entertainment" on offer. And with more of us taking home-entertainment gadgets with us (95 per cent apparently don't leave home without a gadget of some sort) we expect to be able to use them in the room.
